摘要:
A diplexer for a reflector antenna includes a common circular signal waveguide to transmit and receive signals. The signal waveguide includes first and second ends with a common port provided at the first end. A waveguide arrangement is disposed coaxially relative to the signal waveguide in the region of the second end of the signal waveguide. A cylindrical coupler section is disposed between the first and second ends of the signal waveguide, and connects the waveguide arrangement to the common signal waveguide. In order to create a first and second coaxial waveguide port, the waveguide arrangement includes a first circular waveguide, an inner conductor is disposed inside, in which a first signal can propagate when the diplexer is operating, and a second circular waveguide, surrounding the first waveguide, in which a second signal can propagate at a lower frequency than the first signal when the diplexer is operating.

A signal branch for use in a communication system, in particular in a reflector antenna, for the transmission of microwave signals is provided. The signal branch includes a common signal wave guide for transmitting a transmission signal and a received signal that has one first end and one second end as well as an exterior and interior. Moreover, a plurality of transmission signal wave guides is provided for feeding the transmission signal, with the transmission signal wave guides being disposed on the exterior of the common signal wave guide in a symmetrically distributed manner and each being communicatively connected to the common signal wave guide. A plurality of receiver signal wave guides is provided for transmitting the received signal, with the receiver signal wave guides being symmetrically adjacent to the second end of the common signal wave guide and each being communicatively connected to the common signal wave guide.

An orthomode coupler for an antenna system, particularly for a multi-feed antenna is provided. The orthomode coupler includes a first signal waveguide for a first RF signal that can propagate in the first signal waveguide, along a first axis, as well as a second signal waveguide for a second RF signal that can propagate in the second signal waveguide, along a second axis, where the second axis is disposed parallel to the first axis. Furthermore, the orthomode coupler includes a septum polarizer in which the first and second signal waveguide end, and a common signal waveguide having a third axis, along which a transmission and reception signal can propagate, where the third axis runs parallel to the first and the second axis, and where the common signal waveguide is coupled with the septum polarizer. The common signal waveguide includes a further polarizer.

A business application backend system, such as an Advanced Business Application Programming backend can receive and respond to representational state transfer (RESTful) service requests via both HTTP and Remote Function Call (RFC) protocols. In particular, the backend system extracts the RESTful service requests and fulfills the extracted requests using a protocol-independent resource controller. Related apparatus, systems, techniques and articles are also described.

Particular embodiments described herein provide for an electronic device that can be configured to receive data in a data flow, extract a data visa from the data flow, wherein the data visa is related to the data, and determine a reputation of the data from the data visa. The data visa can include reputation determination information obtained by previous network elements in the data flow. In addition, the electronic device can update the data visa, and communicate the updated data visa and data to a next network element in the data flow.

Systems and methods of facilitating trades of instruments are provided. A master node and a plurality of intermediate nodes store counterparty credit matrices. Trades are executed based on the information stored in these matrices. The systems and methods allow selection of trading options that not only accept or reject a trade, but also can indicate a credit status to be assigned to a counterparty to the trade.
